  • Description

    The RESISTOMAT® model 2329 is particularly suitable for fast measurements of low resistances in automated processes. Up to 50 measurements per second can easily be performed. The device complies with the latest CE guidelines and is designed for laboratory use as well as heavy-duty industrial applications. 

    A 2-fold and 4-fold comparator with switching outputs has been included for classifi cation and selection; this feature is particularly useful for serial tests. 

    One special application involves the measurement of contact resistances (dry-circuit measurement); the load voltage in this case is limited to 20 mV in order to prevent fritting (DIN IEC 512). The RS232 (standard) and IEEE488, USB and Ethernet (option) computer interfaces allow the set-up of fully automatic testing stations. The PLC interface allows easy integration into your production process control.

    Typical applications are resistance and conductivity measurements on:

    • Fuses
    • Airbag triggers
    • Coils for the automobile industry and electrical engineering
    • Plug-in contacts and switches
    • Commutator welded joints
    • Meter samples in cable manufacture
    • Circuit-board conductors etc.

    The device operates on the basis of proven 4-wire technology which corrects any incoming line or contact resistances.
    The measurement lines are checked by an integrated cable rupture monitor. Needless to say, the functions include temperature compensation for various test substances such as copper, brass, tungsten etc. Temperatures are measured by a Pt 100 sensor or infrared sensor (pyrometer) with analog outputs or any temperature transmitter e.g. thermocouple.
    For measuring test objects with low inductances, a special measurement input protection was developed to prevent voltage peaks from damaging the device when test objects are disconnected.

    If objects need to be tested for several different parameters by an automatic measurement system, you can store up to 32 device settings such as measurement ranges, limiting values, temperature coeffi cients etc. These settings are called up via a bit pattern (5 bits). Naturally, all device settings can also be made via the RS232 (standard) or IEEE488, USB and Ethernet interfaces (option).

    The integrated data logger can be used during serial measurements to store up to 20 000 measurement values which can be divided into 32 individual blocks. A digital filter is available for preselecting the measurement values to be stored. The evaluation menu of the stochastic data logger displays the maximum, minimum and average values as well as the standard deviation.
